Do you understand the three major causes of pituitary adenoma
A pituitary adenoma is a kind of multiple tumors, which brings many inconveniences to people's life, and the etiology of pituitary adenoma has become the focus of people's attention.
In the daily life we should pay more attention to some details, so that can be very good to prevent the occurrence of pituitary adenoma,
the following by introducing the etiology of pituitary adenoma: First, vascular factors: pituitary adenoma in the blood vessels rich, irregular blood sinus formation, blood sinus wall, tumor volume increase caused by the increase of local pressure caused by blood vessel rupture bleeding.
Modern angiography has confirmed that the blood vessels in the pituitary adenoma are smaller and different in diameter than the normal glands.
Under the electron microscope, these vessels were immature, the basement membranes were ruptured or segmental, and the peripheral space was compressed by plasma proteins and erythrocytes, which were the basis of pituitary adenoma hemorrhage.
Second, the type of tumor: prolactin adenoma, this is not only because it is more common in the pituitary adenoma, and because the tumor volume is generally larger, easy to cause local blood circulation and blood supply barrier.
In the past, it is thought that the pituitary apoplexy is more common in the larger adenoma, but it is thought that small adenoma can occur, many small adenoma strokes, the clinical symptom is not obvious, called Subclinical pituitary apoplexy.
Third, external stimulation induced: traumatic pituitary adenoma, if the head by external force, due to the skull and brain movement speed is inconsistent, tumor and neurocranium in the movement of the moment of squeezing or traction, leading to or promote blood vessels bleeding, especially tumor pathological vessels. Radiotherapy for pituitary adenomas can increase blood vessels in the tumor and increase the chance of bleeding. Some experiments show that estrogen can lead to hyperemia of the pituitary gland, prone to pituitary apoplexy.
